Fix CSS typos and remove duplicate country code (#75)

- Fix "transparant" typo in HelpToggle.svelte (should be "transparent")
- Wrap CSS variable references with var() in FileInput.svelte (two instances
  of `color: --pg-text` that should be `color: var(--pg-text)`)
- Remove duplicate 'at' (Austria) entry in MultiInput.svelte allowedCountries
